Or am I missing something.
Not that colony collapse doesn’t worry me, it does. But if I was being baselessly told to fear agriculture production issues, I am super mad.
At least in North America, the "colony collapse" stuff was a livestock phenomenon more than it was a wildlife/ecology issue. Honey bees aren't native to the US; if you see a honey bee in your back yard, there's a pretty good chance that somebody owns it.
Every time I get a decent population we get some cold weather and I don't see them again for a long time.
If anyone has issues with them boring into buildings, there’s an easy solution: stuff a paper bag with some plastic bags and hang it up nearby. The bees will think it’s a wasp’s nest and vacate the area within a few days. I know someone who does this every year and it works like a charm. Which, I suppose in a way, it is.
At any rate, in warm areas of the US there are many feral old world bees.
Recently I saw a talk where the speaker said that if you find any africanized beehives in the wild, you should kill the hive because you don't want the africanized bees to spread. (Or if you have an africanized beehive, re-queen it.) I don't have any, and I'd be loathe to kill bees because I'm quite fond of them, but it's probably good advice.
But also if you're going to try to kill an africanized wild beehive you should use soapy water, with a sprayer, and if the bees attack then you'll spray your attackers with soapy water than that's that.
This is true even in Europe. If memory serves the percentage of "wild" honeybees (feral may be a more fitting adjective) is in the order of 1%.
One of the things you may be missing is that the article is about "efficiency" as opposed to total impact.
"researchers found that 83% of insect visits to bramble flowers were made during the day. While the moths made fewer visits during the shorter summer nights, notching up only 15% of the visits, they were able to pollinate the flowers more quickly."
Moths are doing great work, but they don't have much time to do the work in and they are not doing the bulk of the work. Also it seems that the night pollinators actually may largely work different flowers than the day pollinators so one can't necessarily pick up the load left by the absence of the other.
Maybe before getting emotionally attached to a position (again) you should understand what’s going on.
